The second of two spin-offs launched by the hugely popular television series C.S.I. - CRIME SCENE INVESTIGATION C.S.I. - NEW YORK distinguishes itself with an even darker grittier tone than either of its predecessors by grounding the action in the gloomy aftermath of post-9/11 New York. The always brilliant Gary Sinise anchors the series as sternly professional former-Marine police detective Mac Taylor whose stoic exterior masks the pain of losing his wife in the World Trade Center attacks. Taylors forensics team includes his tough-as-nails partner Stella Bonasera (Melina Kanakaredes) the sexy but street-smart investigator Aiden Burn (Vanessa Ferlito) no-nonsense tough guy Don Flack (Eddie Cahill) smart-aleck detective Danny Messer (Carmine Giovinazzo) and the briskly efficient coroner Sheldon Hawkes (Hill Harper). Bathed in sombre blue-tinged cinematography the spin-off emphasizes well-drawn character development without sacrificing any of the grisly criminal and scientific elements that made its parent show such a smashing success. Presented here is a selection of episodes from the shows fourth series.
